Question

An isosceles triangle has an angle that measures 128°. Which other angles could be in that Isosceles triangle? Choose all that apply.

Answer 1

Given:

Given angle is 128 degree.

In Isosceles triangle two angles are equal.

Let the angle be x.

Sum of the angles in a triangle is 180 degree.

`\begin{gathered} 128+x+x=180 \\ 2x=180-128 \\ 2x=52 \\ x=26^(\circ) \end{gathered}`

Other angles in an Isosceles triangle is 26 degree.
